Verbena plant named ‘Duempbuc12’

ABSTRACT

A new and distinct cultivar of  Verbena  plant named ‘Duempbuc12’, characterized by its semi-upright and mounding plant habit; vigorous growth habit; freely branching habit; freely flowering habit; and large dark violet and white-colored flowers that are held above and beyond the foliar plane in mounded umbels.

Botanical designation: Verbena hybrida.

Cultivar denomination: ‘DUEMPBUC12’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Verbena plant, botanically known as Verbena hybrida and hereinafter referred to by the name ‘Duempbuc12’.

The new Verbena plant is a product of a planned breeding program conducted by the Inventor in Rheinberg, Germany. The objective of the breeding program is to create new vigorous Verbena plants with numerous large and attractive flowers.

The new Verbena plant originated from a cross-pollination made by the Inventor in July, 2009 in Rheinberg, Germany of a proprietary selection of Verbena hybrida identified as code number V08-3242-001, not patented, as the female, or seed, parent with a proprietary selection of Verbena hybrida identified as code number F-22-16, not patented, as the male, or pollen, parent. The new Verbena plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Rheinberg, Germany in May, 2011.

Asexual reproduction of the new Verbena plant by terminal cuttings in a controlled greenhouse environment in Rheinberg, Germany since July, 2011 has shown that the unique features of this new Verbena plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Verbena have not been observed under all possible environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Duempbuc12’. These characteristics in combination distinguish ‘Duempbuc12’ as a new and distinct Verbena plant:

-   -   1. Semi-upright and mounding plant habit.     -   2. Vigorous growth habit.     -   3. Freely branching habit.     -   4. Freely flowering habit.     -   5. Large dark violet and white-colored flowers that are held         above and beyond the foliar plane in mounded umbels.

Plants of the new Verbena differ from plants of the female parent selection primarily in branching habit as plants of the new Verbena are more freely branching than plants of the female parent selection. In addition, plants of the new Verbena and the female parent selection differ in flower color as plants of the female parent selection have lavender-colored flowers.

Plants of the new Verbena differ from plants of the male parent selection primarily in flower color as plants of the male parent selection have purple-colored flowers.

Plants of the new Verbena can be compared to plants of the Verbena hybrida ‘Lan Roypureye’, disclosed in U.S. Plant Pat. No. 15,610. In side-by-side comparisons conducted in Rheinberg, Germany, plants of the new Verbena differed from plants of ‘Lan Roypureye’ in the following characteristics:

-   -   1. Plants of the new Verbena were more vigorous than plants of         ‘Lan Roypureye’.     -   2. Plants of the new Verbena had shorter internodes than plants         of ‘Lan Roypureye’.     -   3. Plants of the new Verbena had longer leaves than plants of         ‘Lan Roypureye’.     -   4. Plants of the new Verbena were more freely flowering than         plants of ‘Lan Roypureye’.     -   5. Plants of the new Verbena had larger flower umbels than         plants of ‘Lan Roypureye’.     -   6. Plants of the new Verbena and ‘Lan Roypureye’ differed in         flower color as plants of ‘Lan Roypureye’ had red purple-colored         flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Verbena plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Verbena plant.

The photograph on the first sheet is a side perspective view of a typical flowering plant of ‘Duempbuc12’ grown in a container.

The photograph on the second sheet is a close-up view of typical inflorescences of ‘Duempbuc12’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations, measurements and values describe plants grown in 12-cm containers during the summer in a glass-covered greenhouse in Rheinberg, Germany and under cultural practices typical of commercial Verbena production. During the production of the plants, day and night temperatures averaged 18° C. and light levels averaged 4,500 lux. Plants were pinched one time three weeks after planting and were ten weeks old when the photographs and the description were taken. In the description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
